  • Pentlandite Wikipedia

    Pentlandite is an iron–nickel sulfide, (Fe,Ni) 9 S 8.Pentlandite has a narrow variation range in Ni:Fe but it is usually described as having a Ni:Fe of 1:1. It also contains minor cobalt, usually at low levels as a fraction of weight.. Pentlandite forms isometric crystals, but it is normally found in massive granular aggregates.It is brittle with a hardness of 3.5–4 and specific gravity of

    Pyrrhotite is found with pentlandite in basic igneous rocks, veins, and metamorphic rocks. It is also often found with pyrite, marcasite, and magnetite. It has varying magnetic powers, depending on the number of Fe vacancies in the crystal structure. A related species with no vacancies (and therefore non-magnetic), is called troilite and has
